Work Equation

Reference from the original Physics I textbook.

Work Equation

For a constant force: W=F→·Δr→. In general, W = ∫F⃗ · dr⃗.

With magnitudes and angles: W=|F→||d→|cosθ

 

W= Work (J)​
F→= Force (N)​
d→= Displacement (m)​
θ= Angle between F→ and d→

  • Mechanical work

    Mechanical work is energy transferred by a force through displacement of its point of application. For a constant force on a particle, it depends on the force component along the particle’s displacement, and it can be positive, negative, or zero. For example, a magnetic force perpendicular to a particle’s displacement does zero work on that particle.
